An excerpt:
How high does the MAG fly?
How much space does it take in the sky?
- The MAG flies at heights between 200 and 300 m. The flight does not use much space! The MAG flies inside a plane surface. About 500m span. Unlike a kite, the MAG does not go up and down in the air. Just from left to right and back.
All this could lead to a better optimization of the Power to space use ratio. Indeed straight paths, whether vertical or horizontal, are easiest to stack by units flying above or below each other, and side by side, like this (video), in order to harness the whole frontal airspace.
